The float type in Python designates floating-point numbers. To create these types of numbers, you can also use literals, similar to what you use in math. However, in Python, the dot character (.) is what you must use to create floating-point literals:...

Let's understand why this "math error" occurs in different math module functions in a python program. What is a math domain error? The pythonmath domain erroroccurs whenever we try to calculate or do some math operations on some mathematicallyundefinedvalues. i.e the values upon which the ma...
This applies to various common tasks, such as file handling, multi thread, multi process, networking, system operations, algorithms, and more. For example: For those who are new to Python and have only dabbled in basic microcontroller development, they might wonder why there are no examples ...

In this part of the PyCairo tutorial, we draw some basic primitives. We use fill and stroke operations, dashes, line caps, and line joins. Lines Lines are very basic vector objects. To draw a line, we use two method calls. The starting point is specified with themove_tocall. The endin...

A basic, yet powerful calculator app built using Python. This project demonstrates the use of fundamental programming concepts such as functions, conditionals, and loops. It allows users to perform basic arithmetic operations including addition, subtraction, multiplication, division and more. Instructions...
A simple interactive BASIC interpreter written in Python 3. It is based heavily on material in the excellent bookWriting Interpreters and Compilers for the Raspberry Pi Using Pythonby Anthony J. Dos Reis. However, I have had to adapt the Python interpreter presented in the book, both to work ...
